Unformatted text preview: Notice that the percentages add up to 100.00%; this provides a check that the calculations are correct. EXAMPLE 3.9 Carvone is a substance that occurs in two forms having different arrangements of the atoms but the same molecular formula (C lO H I4 0) and mass. One type of carvone gives caraway seeds their characteristic smell, and the other type is responsible for the smell of spearmint oil. Compute the mass percent of each element in carvone. Solution Where are we going? To find the mass percent of each element in carvone What do we know? ./ Molecular formula, C lO H 14 What information do we need to find the mass percent? ./ Mass of each element (we'll use 1 mol carvone) ./ Molar mass of carvone...
